Description

Technical Field

[0001] This utility model relates to the field of microneedle sensor technology, and in particular to a microneedle sensor with a buffer structure. Background Technology

[0002] Microneedle sensors are high-resolution tools used for real-time monitoring of signaling molecules within living organisms. By inserting microneedles, they can directly detect changes in chemical substances inside the body, such as neurotransmitters and metabolites. Microneedle sensors typically consist of microneedles inserted into the body, while the sensing layer identifies and converts target signaling molecules. Currently, the length of the microneedles in microneedle sensors is fixed. When used, the excessive length of the microneedles causes severe skin irritation and pain upon initial insertion, necessitating improvement. Utility Model Content

[0041] A microneedle sensor with a buffer structure includes a mounting plate 1, and further includes: multiple fixing slots 2, which are disposed on and fixedly connected to the mounting plate 1; a housing 3, which is disposed on and fixedly connected to the mounting plate 1; a cover plate 4, which is disposed on and fixedly connected to the housing 3; a buffer ring 5, which is disposed on and fixedly connected to the mounting plate 1; and a buffer mechanism, which is disposed on the cover plate 4 and the mounting plate 1, for reducing stimulation and achieving buffering.

[0042] refer to Figure 1 and Figure 2In a preferred embodiment, the buffer mechanism includes: a mounting part disposed on the mounting plate 1, the cover plate 4, and the outer shell 3; a buffer part disposed on the mounting part; and a sensing part disposed on the buffer part.

[0043] In this configuration, the mounting section is used to install the buffer mechanism; the buffer section is used to adjust the length of the needle and the speed of subsequent continuous insertion of the micro needle 14, thereby reducing the stimulation and achieving the purpose of buffering; and the sensing section is used to realize the sensing function.

[0044] refer to Figure 2 and Figure 3 In a preferred embodiment, the mounting part includes: a mounting groove 6, which is disposed on the cover plate 4 and fixedly connected to the cover plate 4; a mounting member 7, which is disposed on the mounting plate 1 and fixedly connected to the mounting plate 1; and multiple sliding grooves 8, which are disposed on the outer shell 3 and fixedly connected to the outer shell 3.

[0045] In this configuration, the mounting groove 6 is used in conjunction with the mounting piece 7 to fix both ends of the screw rod 10; the sliding groove 8 is used to prevent the connecting ring 12 from rotating or shifting during lifting operations.

[0046] refer to Figure 4 and Figure 5 In a preferred embodiment, the buffer part includes: a knob 9, which is disposed on the cover plate 4 and fixedly connected to the cover plate 4; a spiral rod 10, which is disposed between the knob 9 and the mounting member 7 and fixedly connected to the knob 9, and the spiral rod 10 is rotatably connected to the mounting member 7; and a moving member 11, which is disposed on the spiral rod 10 and threadedly connected to the spiral rod 10.

[0047] In this configuration, the knob 9 is used to drive the screw rod 10 to rotate, and the knob 9 is made of stainless steel, which has good wear resistance. The surface of the knob 9 is provided with grooves to increase friction and prevent slippage, making it easy to rotate the knob 9. The screw rod 10 is used to drive the moving part 11 to perform lifting and lowering operations. The moving part 11 is used to drive the sensing layer 13 to perform lifting and lowering operations.

[0048] refer to Figure 3 and Figure 5 In a preferred embodiment, the sensing unit includes: a sensing layer 13 disposed on the moving member 11 and fixedly connected to the moving member 11; a connecting ring 12 disposed on the sensing layer 13 and fixedly connected to the sensing layer 13; and a micro needle 14 disposed on the sensing layer 13 and fixedly connected to the sensing layer 13.

[0049] In this configuration, the sensing layer 13 is used to detect changes in chemical substances inside the body; the connecting ring 12 is used to fix the sensing layer 13 to prevent rotation and displacement when the sensing layer 13 is moved; and the microneedle 14 is used to be inserted into the patient's body. The microneedle 14 is made of stainless steel, which has good mechanical properties and biocompatibility and will not break when inserted into the body, thus avoiding health problems.

[0050] This device incorporates a buffer mechanism that pre-adjusts the length of the microneedle 14 before using the microneedle sensor, ensuring a shallow insertion depth and reducing skin irritation. The microneedle 14 is then inserted into the body at a uniform and slow pace to prevent severe pain. Furthermore, the use of stainless steel for the microneedle 14 prevents breakage within the body, thus minimizing safety risks.

[0051] Working principle: When using this device, first turn knob 9, which will drive the screw rod 10 to rotate. The screw rod 10 drives the moving part 11 to move up and down on the screw rod 10. The moving part 11 drives the sensing layer 13 and the microneedle 14 to move up and down, allowing the microneedle 14 to slowly extend and exceed the buffer ring 5 by a small distance. Then, insert the microneedle 14 into the patient's skin until the buffer ring 5 contacts the patient's skin. Then turn knob 9 again, which will drive the screw rod 10 to rotate. The screw rod 10 drives the moving part 11 to move up and down on the screw rod 10. The moving part 11 drives the sensing layer 13 and the microneedle 14 to move up and down, allowing the microneedle to slowly and continuously penetrate into the patient's body. After knob 9 can no longer be turned, the microneedle is fully inserted into the patient's body and detects changes in the chemical substances inside the biological body through the sensing layer 13.

[0052] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
